Chinese shipbuilder reveals breakthrough technology

One of China's major shipbuilders said it has developed cutting-edge propulsion technology that will bring the nation closer to its goal of modernizing its shipping and naval fleets.

China Shipbuilding Industry Corp said its Wuhan Institute of Marine Electric Propulsion finalized its integrated electric propulsion technology in mid-July. It said the in-house development will help the nation wean itself off the longstanding dependence on imported parts in manufacturing ships.

Most surface vessels in China use mechanical transmissions and are propelled by a motor or an engine spinning a propeller. Many Western countries have adopted integrated electric propulsion, in which gas turbines or diesel generators produce electricity that powers electric motors.
